Subject: mac80211: don't update dev->trans_start
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ce5b071a456beea13a893fcc73f47998bf7ceb35;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mac80211: don't update dev->trans_start

This isn't necessary any more as the stack will automatically
update the TXQ's trans_start after calling ndo_start_xmit().
